Raft Benchmark

Benchmark program to measure the performance of the pure Raft replication logic, excluding disk I/O and state machine overhead.

It uses

• In-memory Raft log store, based on std::map.
• Empty state machine which does nothing on commit.

How to Run

• Parameters

$ ./raft_bench <server ID> <IP address:port> <benchmark duration in second> <input traffic (IOPS)> <number of threads> <payload size in byte> <server 2 IP address:port> <server 3 IP address:port> ...

• Run followers first

$ ./raft_bench 2 10.10.10.2:12345 3600

$ ./raft_bench 3 10.10.10.3:12345 3600

It will run follower 2 and 3 for an hour.

• Run leader

$ ./raft_bench 1 10.10.10.1:12345 30 100 2 256 10.10.10.2:12345 10.10.10.3:12345

It will

• Run the benchmark for 30 seconds.
• Target traffic: 100 requests/second.
• 2 client threads.
• Each payload size will be 256 bytes.

After each run, all followers MUST BE killed and then re-launched.
